To integrate Bloomberg and Excel when you download data, you will need to install the Excel add-in on the Bloomberg terminal you are using. The add-in is installed to your profile and not the computer itself.
Open Excel from the desktop icon.
On the computer task bar, select Start > All programs > Bloomberg > Install Office Add-in.
Click Install and a small confirmation box will appear.
Once the install in finished, close Excel.
Open Excel again and the Bloomberg tab will now appear on the taskbar.
